Usually I use the good ole 2bar map from the 89 T/A when doing LS1 SD 2 bar tuning . This time I am trying the Cobalt Ion sensor part # 12615136 which is a new number for that sensor. Its the brown face "plug and play"style sensor. I searched some values the other day off this site and they where;207.625 for scaler9.0 for offsetThose values yielded a map reading of 105 kpa for atmospheric ... Which was 99 prior with factory 1 bar. I figured I would adjust the scaler to bring the number down but not value within 70 made a change. For the he'll of it I put the value back to the 207.625 and made the offset stock... It made changes to the scaler work. After dialing the VE bellow 105 kpa I did a light WOT pull in which it appeared the map wouldnt read past 99 kpa and throws the car into REP. It's a 2004 Corvette with a 2010 camaro LS3 and a 2010 Corvette E Force roots blower. I know it should be over 105 kpa as soon as I crack it...Can anyone confirm the correct values for that sensor or post a Ion stock file? Also I believe this is a BARO sensor by definition and not a MAP.... Not sure what it matters it's pressure....Gonna go back to what worked if I dont clarify this.... ThanksHT
